“Win” Foreign Coins when you “Buy” Cloverine Salve to “Sell”

This a genius comic ad. It tricks kids into selling Cloverine Salve by thinking they are winning a contest for some foreign coins (that I am sure are worth about 5 cents). Now that you got your foreign coins, you just need to go door to door selling their fine smelling salve. What a bargain. Can you name all the countries?
